What is the main function of carbohydrates?

1. Provide essential fatty acids

2. Break down basic chemical sugars that supply energy for the body

3. Enhance nutrient absorption

4. Maintain healthy skin

The correct answer is: Break down basic chemical sugars that supply energy for the body

The primary function of carbohydrates is to break down into simple sugars, which then supply energy for the body. Carbohydrates are one of the essential macronutrients, alongside proteins and fats, and play a crucial role in providing the energy that fuels various bodily functions and activities. Upon consumption, carbohydrates are metabolized into glucose, which is the body’s primary energy source for cells, tissues, and organs. This energy is especially vital for maintaining the function of the brain, which relies heavily on glucose as a source of energy. While vitamins and minerals enhance nutrient absorption or contribute to skin health, those are not the main roles of carbohydrates. Additionally, carbohydrates do not provide essential fatty acids; rather, those are found primarily in fats and oils. Thus, the correct option emphasizes the vital role of carbohydrates in energy production within the body.
